JVM execution slow when run in debug mode with debug agent attached

Issue

• Slow class loading when running JVM in debug mode

  java -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n ClassName
  

• During remote debugging- (agentlib:jdwp), an application spends a lot of time in JVM internals like Unsafe.defineAnonymousClass or Class.getDeclaredConstructors.Sometimes this happens on EDT and UI freezes occur.
